Gallium Oxide is a highly insoluble thermally stable Gallium source suitable for glass, optic and ceramic applications. The precipitation of the hydrated form of gallium oxide is caused by the neutralization of acidic or basic gallium salt solution. Oxide compounds are not conductive to electricity. However, certain perovskite structured oxides are electronically conductive finding application in the cathode of solid oxide fuel cells and oxygen generation systems. They are compounds containing at least one oxygen anion and one metallic cation. They are typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. Metal oxide compounds are basicanhydrides and can therefore react with acids and with strong reducing agents in redox reactions. Gallium Oxide is also available in pellets, pieces, powder sputtering targets, tablets, and nanopowder (from American Elements' nanoscale production facilities). See Nanotechnology for more nanotechnology applications information. Gallium Oxide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered. Additional technical, research and safety (MSDS) information is available.
Gallium is a Block P, Group 13, Period 4 element. The number of electrons in each of Gallium's shells is 2, 8, 18, 3 and its electronic configuration is [Ar] 3d10 4s2 4p1. In its elemental form gallium's CAS number is 7440-55-3. The gallium atom has a radius of 122.1.pm and it's Van der Waals radius is 187.pm. Gallium is not toxic. Gallium is one of three elements that naturally occur as a liquid at room temperature. The other two are mercury and cesium. The application of gallium that has received the most attention is the production of semiconducting compounds. Of these, the most important are the compounds of gallium with antimony, arsenic or phosphor. Nowadays gallium arsenide (Ga-As) is undoubtedly the most used. This compound is used in the production of several electronic parts such as diodes and transistors, made for voltage rectification, signal amplification, etc. Other gallium arsenide applications are the semiconductor "lasing" and microwave generation and also in sensors to measure temperature, light or magnetic field. Researchers at Northwestern University's Center for Quantum Devices recently developed a Gallium based semiconductor material that will advance infrared camera technology. Gallium does not exist by itself in nature and is sourced commercially from bauxite and sphalerite. Gallium was first discovered by Hans Christian Oersted in 1825. See Gallium research below.
